I agree with Maciej here: this kind of stuff can also happen with normal initialization code and
uses of units in the implementation part. In this case the programmer must simply be very careful.
Though in your example I think unit1 is always initialized first as it does not depend on unit2. The
problem might pop up though if you use unit2 in the implementation part of unit1.
